Currently, when polishing such workpieces, workers usually rely on handheld grinders to polish the workpieces. When polishing the workpiece, the workers turn on the grinder and then bring the grinding disc on the grinder close to the workpiece to grind the workpiece. This process is not only labor-intensive, but also inefficient and inconvenient to use. Utility Model Content

Then, the clamping mechanism is used to rotate the workpiece through the rotating mechanism. Then, the floating mechanism is used to drive the grinding blade mounting seat to approach the workpiece through the dual-axis module.
